Example one

As shown in figures 1-3, the explosion-proof device for acetylene soot-blowing system comprises

Further, as shown in fig. 1 and 3, the method includes:

the explosion-proof pipe 100 is used for being connected with a pipeline, and two ends of the explosion-proof pipe 100 are respectively provided with a connecting plate 1001 for communicating the pipeline;

the non-return component 1 is used for preventing the non-return component 1 from being tempered and is arranged in the explosion-proof pipe 100;

the check assembly 1 includes:

the non-return mechanism 11 is used for preventing backfire and controlling the non-return mechanism 11 of the opening/closing of the explosion-proof pipe 100 to be arranged in the explosion-proof pipe 100; and

and the escape-proof mechanism 12 is connected with the check mechanism 11, and the escape-proof mechanism 12 is connected with the check mechanism 11.

Further, as shown in fig. 5, the check mechanism 11 includes:

the first channel 111 is arranged in the explosion-proof pipe 100 and communicated with one end of the connecting plate 1001;

a second passage 112, the second passage 112 communicating with the first passage 111;

a check 113 for blocking the check 113 of the first passage 111 is provided in the second passage 112;

when the gas-liquid separator is used, the check block 113 is adsorbed by the pressure in the pipeline and blocked at the outlet of the first channel 111, when the gas amount in the pipeline is enough, the check block 113 can be flushed into the second channel 112, and the gas can be sprayed out from the second channel 112;

subsequently, the gas may flow back, and the gas may cause explosion of the pipe if returning to the inside of the pipe, so that the thrust generated by the gas flowing back pushes the check block 113 back to the first passage 111 again, thereby performing sealing, effectively preventing the gas from flowing back, and prolonging the service life of the gas.

Further, the diameter of the check block 113 is larger than that of the first channel 111, so that a better sealing effect is achieved.

Further, the check block 113 is movable in the second channel 112 and can be forced to move in the second channel 112, so that the rigid damage to the check block 113 is reduced.

Further, the check block 113 is a spherical structure, which can be used to block the first passage 111 conveniently, and in the process of gas backflow, no matter which suspension falls, the check block can seal the first passage 111.

Further, the escape prevention mechanism 12 includes:

the first limiting column 121 is used for limiting the first limiting column 121, which is used for limiting the check block 113 to rush out of the second channel 112, is arranged in the second channel 112;

Further, as shown in fig. 4, the first position-limiting column 121 and the second position-limiting column 122 are connected in a cross manner to form a cross structure;

after the explosive gas enters from the first passage 111, due to the enough pressure, the explosive gas can continuously advance forwards until the check block 113 at the outlet of the first passage 111 is broken through, at the moment of breaking out, the check block 113 is moved towards the direction of escaping from the second passage 112 by the impulse force, however, under the interception action of the first limiting column 121 and the second limiting column 122, the check block 113 is suspended in the second passage 112, so that during the gas backflow process, the check block 113 is subjected to the pressure again and flows back to the first passage 111, and the diameter of the first passage 111 is smaller than that of the second passage 112, so that the check block 113 can seal the first passage 111 to prevent the backflow of the gas, thereby causing the secondary explosion.

Example two

As shown in fig. 5, where the same or corresponding components as in the first embodiment are given the same reference numerals as in the first embodiment, only the differences from the first embodiment will be described below for the sake of convenience. The second embodiment is different from the first embodiment in that:

further, as shown in the figure, a receiving portion 1111 is disposed at a position where the first channel 111 contacts the check block 113.

Further, the connection part of the second channel 112 and the first channel 111 is provided with a jet shape;

the receiving portion 1111 may be attached to an outer wall of the check block 113, so that the check block 113 is closely attached to the receiving portion 1111, thereby increasing the sealing performance of the check block 113 with respect to the first passage 111, and the connection portion of the second passage 112 and the first passage 111 may be formed in a spray shape, thereby facilitating the check block 113 to be flushed away from the outlet of the first passage 111 by the explosive gas.

Further, the first limiting column 121 and the second limiting column 122 are made of stainless steel, and are 304 stainless steel structures, wherein 304 stainless steel is a common material in stainless steel, and has a density of 7.93 g/cm for harvesting; also known in the industry as 18/8 stainless steel, means containing more than 18% chromium and more than 8% nickel; the high temperature resistant 800 ℃ has the characteristics of good processing performance and high toughness, and can prevent the check block 113 from escaping from the second channel 112 and also avoid damaging the check block 113.
